Use a Mac Tutorials: Airdrop is an app that comes with OS X Lion Macs. It allows you to connect with other computers and perform drag-and-drop file sharing, without having to set up a network. As long as the computers involved are WiFi enabled, within your vicinity, and they both have Airdrop, they can exchange files. The files are secured with TLS encryption, and a firewall stops anyone from accessing your computer over the connection.

Airdrop will work with other Macs, too: the Mac Pro (from mid-2010 on, or 2009 with AirPort Extreme card), the MacBook Pro (late 2008 or newer), the iMac (early 2009 or newer), Mac mini (mid-2010 or newer), the MacBook Air (late 2010 or newer) the MacBook (late 2008 or newer), the iMac (early 2009 or newer).

Here’s a video tutorial showing you how to use Airdrop:

Go to the Go tab on the upper left menu on your screen. Click on it, and scroll down to Airdrop.

If you don’t see it, your computer is not Airdrop compatible.

Step 2:

Click on Airdrop and you will see a list of all Airdrop-enabled computers nearby.

You will see an avatar/photo of the user and his or her user name.

Step 3:

Open up the file you want to send. Drag and drop that file onto the person’s name/image.

You will see a dialog box that asks you if you want to send that file to that person.

Step 4:

Click “Send.”

You will see “Waiting for (username) to accept…” At that point, you can cancel the transfer, or wait for him or her to accept it.

Then you’ll see the transfer box, and it will close automatically when the transfer is complete.
If a person sends you an Airdrop file, you will get a dialog box pop up that says “(Username) wants to send you file (filename).”

You have three choices: you can click “Save and Open,” “Decline,” or “Save.”

If you click “Save and Open,” the file will open automatically once the transfer is complete. If you click “Save” and you want to access the file, you can find it in your Downloads folder.
